If you want to run bigger and wider tires on your Jeep JK Wrangler, you really need to do one of two things. One, buy a set of new wheels with less back spacing or two, install a set of high quality wheel spacers which will effectively reduce the 6.25″ of back spacing that your factory wheels have. Of course, if you are someone who really likes the look of factory wheels and would prefer to keep them or, if you’re on a budget and are trying to build up your JK as economically as possible, installing a set of Spidertrax wheel spacers is the answer for you.Made out of 6061 T6 and anodized blue aluminum for corrosion resistance, Spidertrax wheel spacers are designed to be wheel and hub centric and come with pre-installed wheel studs, lugnuts and Red Loctite. Basically, everything you need for proper installation. And, the best part is, they are very affordable and very easy to install.
